The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. The US has made major reductions in NO x emissions, but it’s been nearly 20 years since EPA updated these standards.
The objective of the emission impact analysis was to respond to EPA’s request for comments as to the merits of reducing NO x emissions from heavy-duty trucks by 50 to 90% as outlined in the 6 January 2020 Advance Notice of Proposed Rulemaking (ANPR) of the CTI.

The US Environmental Protection Agency (EPA) has awarded $5 million to the Southern Alliance for Clean Energy (SACE) to help Southern truckers and small businesses to buy cleaner big rigs. Rush Enterprises, Inc. About 8 million are exposed to air quality that violates the federal standards for particulate matter.
Commercial workboat engines are staying in service more than two times longer than predicted by the US Environmental Protection Agency (EPA), according to new research from the Diesel Technology Forum (DTF) and Environmental Defense Fund (EDF). —Ezra Finkin, DTF Policy and Outreach Director. Elena Craft, EDF Senior Director.
Lisa P Jackson, Administrator of the US Environmental Protection Agency, issued a public memo to EPA employees detaling “ seven key themes to focus the work of our agency ” in 2010 and beyond. Jackson wrote that EPA will also focus on improving EPA’s internal operations, from performance measures to agency processes.
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). EPA is seeking input from the public and interested stakeholders. The ANPR provides an opportunity for comment on the extent to which EPA should adopt provisions similar to those expected in the CARB Omnibus proposal.
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. national ambient air quality standards (NAAQS).

Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2 Last year, we introduced a propane autogas engine that was 75% cleaner than the EPA’s emissions standard. grams per brake horsepower-hour (g/bhp-hr). Earlier post.). g/bhp-hr heavy-duty engine standard. g/bhp-hr.
Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.
Refuse and central business district duty cycles show similar in-use emissions performance to the local and near-dock port cycles, while urban dynamometer driving schedule (UDDS) represents the standard cycle the EPA uses for vehicle and fuel emissions testing. g/bhp-hr emission target and averaged between 0.014 and 0.002 g/bhp-hr.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
The EPA sets standards for six principal air pollutants to meet its obligation under the Clean Air Act to protect the health of the American public, including vulnerable populations, by an adequate margin of safety. The ATS recommended standards for O 3 and PM 2.5 The ATS and Marron Institute expect to update the report annually.
FTA’s Low-No Program supports transit agencies in purchasing or leasing low- or no-emission buses and other transit vehicles that use technologies such as battery electric and fuel-cell power to provide cleaner, more efficient transit service in communities across the country.
exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. HEI is an independent, non-profit research institute funded jointly by the US Environmental Protection Agency (EPA) and the worldwide motor vehicle industry. Earlier post.)
These revisions are intended to align California’s reporting requirements with the federal reporting rules recently enacted by the US Environmental Protection Agency (EPA), and to ensure that the information collected by those covered by the cap-and-trade program is of sufficient quality to support the program. Offset Protocols.
On their 100+ mile round trip, these trucks burn diesel fuel that damages the ozone, spews out noxious particulates that seek-out lungs and eyes along with oxides of nitrogen that help create smog, along with other nasty—and toxic—unpleasantness. How much cleaner could the air be if, instead of 50 trucks, it is 500, 1,000 or 10,000.
A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO 2 ), ozone, and particulates (PM 2.5).
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, like i said in the first place, for me, this makes me think of one step in the right direction and makes me think of a greener cleaner future.
EPA regional offices will award the assistance agreements for selected projects; EPA expects to make around 80 awards. Reducing emissions from diesel engines remains one of the most important air quality challenges facing the country, according to the EPA. Funding will be in the form of cooperative agreements or grants.
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Since its launch in 2011, the regulation has generated a multitude of unique approaches for cleaner fuels. In 2014 ARB will consider extending the LCFS, with more aggressive targets for 2030.
The US Environmental Protection Agency (EPA) is proposing to retain, without changes, the existing, more stringent 2015 National Ambient Air Quality Standards (NAAQS) for ozone. From 2017 to 2019, ozone concentrations fell 4%. From 2017 to 2019, ozone concentrations fell 4%. Background.
